Oasis were an English rock band formed in Manchester in 1991. Developed from an earlier group, the Rain, the band originally consisted of Liam Gallagher (vocals, tambourine), Paul "Bonehead" Arthurs (guitar), Paul "Guigsy" McGuigan (bass guitar), and Tony McCarroll (drums). Upon returning to Manchester, Liam's older brother, Noel Gallagher (lead guitar, vocals) joined as a fifth member, which formed the band's core and settled line-up. During the course of their existence, they had various line-up changes. Oasis signed to independent record label Creation Records in 1993 and released their record-setting debut album Definitely Maybe (1994). The following year the band recorded (What's the Story) Morning Glory? (1995) with drummer Alan White, in the midst of a chart rivalry with Britpop peers Blur. (What's the Story) Morning Glory? became one of the best-selling albums of all time, selling over 22 million copies worldwide and the Gallagher brothers were featured regularly in tabloid newspapers for their sibling disputes and wild lifestyles. In 1996, Oasis performed two nights at Knebworth for an audience of 125,000 each night, which were at the time the largest outdoor concerts in UK history. 2.5 million people applied for tickets, which remains the highest demand for a show in British history. In 1997, Oasis released their third album, Be Here Now (1997); although it was the fastest-selling album in UK chart history, and went on to sell 8 million copies, its popularity tapered off quickly. McGuigan and Arthurs left Oasis in 1999 as the band released Standing on the Shoulder of Giants (2000). They were replaced by former Heavy Stereo guitarist/frontman Gem Archer and former Ride guitarist/frontman Andy Bell. Their fifth studio album Heathen Chemistry was released in 2002. In 2004, White left, leaving them as a four-piece, with the addition of the Who drummer Zak Starkey as an unofficial recording and touring fifth member. They found renewed success and popularity with Don't Believe the Truth (2005). Following the recording of the band's seventh album Dig Out Your Soul in May 2008, Starkey departed from the band. Chris Sharrock was recruited as a touring member, and Oasis did their last tour as a collective band. During the tour the Gallagher brothers' deteriorating relationship led to Noel Gallagher announcing his departure in August 2009, after a backstage altercation with Liam. The rest of the band, led by Liam, decided to continue, under the name Beady Eye, until their breakup in 2014. Noel formed a solo project, Noel Gallagher's High Flying Birds.
